Question 1

What is मृत्तिका (Earth)?

Accepted Answer

Mr̥ttikā (Earth), encompassing *m मिट्टी* (Miṭṭī), *भूमि* (Bhūmi), and *मृदा* (Mr̥dā), denotes earthen materials utilized extensively in Indic heritage architecture since prehistoric times. Its variable composition, sourced from diverse geological formations across the Indian subcontinent, includes clay minerals, silt, and sand, influencing its density (1400-2200 kg/m³) and porosity (20-50%). Traditional processing methods involved quarrying suitable *m मिट्टी* (Miṭṭī) from riverbeds or fields, followed by mixing with organic binders like straw to enhance tensile strength and reduce shrinkage (5-15%) [2].

Adobe bricks and rammed earth (*कच्चा* *घर*) were prevalent construction techniques, exemplified in Harappan settlements and later structures under the Maurya and Gupta Dynasties. *मृत्तिका* (Mr̥ttikā) served as walls, floors, and roofs, offering high thermal mass and insulation (thermal conductivity: 0.2-1.5 W/mK). Conservation efforts for heritage sites necessitate understanding the material's degradation mechanisms and employing compatible repair materials, often involving re-application of traditional *मृत्तिका* (Mr̥ttikā) plasters [3]. *भट्टी* (Bhaṭṭī) hearth furnaces [1] were used to create fired bricks, a more durable alternative.
